NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 485,120, dated October25, 1892.

Application led .Tune 25, 1892.

To all whom it' may concern.-

Be it known that I, ISRAEL WOLFE, acitizen of the United States, and aresident of Goshen, in the county of Elkhart and State of Indiana, haveinvented certain new and useful Im provernents in Nut-Locks; andI dohereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification,andin which- Figure lis a perspective View of my improved nut-lockcomplete as applied to a railjoint. Fig. 2 is a similar view of thejoint and washer-plate, but with the locking-plate proper removed. Fig.3 is a perspective detail view of the washer-plate. Fig. 4 is a similarview of the locking-plate from the side facing the washer-plate. Fig. 5is a transverse sectional view through the rail-joint and lock on line xin Fig. l, and Fig. 6 is a similar View on the parallel transverse planeindicated by the broken line marked y y.

Like letters of reference denote corresponding parts in all the gures.

This invention relates to devices for locking the nuts on the bolts usedin connecting the ends of railway-1'ails in rail-joints; and it consistsin the combination,with the bolts and nuts of the joint, of a removablelocking device of novel construction, as will be hereinafter more fullydescribed and claimed.

Referring to the drawings, the letters A A designate the meeting ends oftwo railwayrails of a rail-joint, B B the bolts, and C C their nuts. Thefish-plates or angle-plates D D are of the usual construction and areplaced one on each side of the joint. After the bolts have been properlyinserted a Washer-plate E is placed upon their proj ect-ing ends, saidplate E having apertures for the insertion of that end of the boltswhichis to receive the nuts. This Washer-plate is of the configurationshown more clearly in Fig. wthat is to say, it consists of a rectangularplate, of iron or other suitable metal, the middle part e of which israised by bending it at both ends, so as to form transverse shoulders oroisets c c, forming, when this washer-plate is placed in posi- SerialNo. 438,023. (No model.)

slot or space e between the raised part e and the adjacent fish-plate D.The shoulders c c are set back a sufficient distance from both ends toclear the nuts C and admit of their being screwed up upon or removedfrom the bolts.

The nut-locking device proper consists ot' a plate F, the upper part ofwhich, of a somewhat reduced length and width, is bent or doubled uponitselt', as shown at G, so as to form a hook-shaped clamp adapted to behooked upon and overlap the middle part or offset e' of thewasher-plate. When the locking-plate F is in this position, it isprevented from slipping off of the washer-plate by lugs or catches ffupon the lower and inner side of plate F, which may be formedconveniently by bending oisets on the lower end of the plate inwardly,so that they will by the spring of thelockingplate when the same isplaced in position slip in under the lower edge of the offset e on thewasher-plate, as illustrated more clearly in Fig. 6, and thereby holdplate F in position. When the locking-plate is in this applied andoperative position, its ends will rnpinge upon the sides of thesquarelyturned nuts C, so as to eiectually prevent them from turning ontheir bolts B and working loose or jarring oft.

In order to easily manipulate the lockingplate, its lower middle part isbent outwardly at right angles, so as to form a projecting tinger-pieceH, by taking hold of which the plate may readily be placed in positionor removed, as the case may be. To remove the device, the lower end ofplate F is by its nger-piece I-I pulled out from the offset c on thewasherplate enough to release its catches ff, when it can be easilyslipped ott said plate.

It will be observed that this device is exceedingly simple andinexpensive in construction, that it can be easily applied and as easilyremoved when desired,`aud that it forms an absolute lock for the nuts onboth sides of the rail-joint.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United Statesl. The combination, with thewasher-plate E, having oi'set e', of the locking-plate F, having theoverlapping part G and provided with IOO the outwardly-projectingfinger-piece H, and inwardly-projectinglugs or catches ff, adapted toengage under the loWer edge of the Washer-plate, substantially as andfor the purpose shown and set forth.

2. The combination,with the rails of a rail- Way-rail joint, of thebolts, nuts, Washer-plate E, having offset e', forming side shoulder cc, and the removable locking-plate F, made of spring metal, having theoverlapping bent part G and provided with the finger-piece H,

and inwardly-projecting catches ff, adapted to engage with the underside of the offset on the washer-plate, substantially as and for thepurpose shown and set forth.

In testimony that I claim the foregoing as my own I have hereunto aixedmy signature in presence of two witnesses.

ISRAEL WOLFE.
